For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figure 1-Figure 3 As shown, in one embodiment, the utility model provides a painting box, comprising a box body 1 and a box cover 2, wherein one end of the box body 1 and the box cover 2 are hinged;

[0042] A first drawing board fixing member 3 is provided on the inner side surface of the box cover 2, and the first drawing board fixing member 3 includes a slide rail assembly 31 and a lower end stopper 32;

[0043] The slide rail assembly 31 includes two symmetrically arranged slide rails 311 and at least one limiting position 312 arranged between the two slide rails 311, and each limiting position 312 is provided with one or more first limiting teeth 3121; a rotating sliding shaft 321 is provided at one end of the lower end limiting member 32, so that the lower end limiting member 32 can rotate around the rotating sliding shaft 321, and the rotating sliding shaft 321 can slide in the slide rail assembly 31;

[0044] Among them, the lower end limit member 32 is provided with a second limit tooth 322 meshing with the first limit tooth 3121 at one end close to the rotating sliding shaft 321; wherein, the lower end limit member 32 can be switched between a first working state and a second working state. In the first working state, the lower end limit member 32 rotates around the rotating sliding shaft 321 to a retracted state, and can slide in the slide rail assembly 31; in the second working state, the lower end limit member 32 rotates around the rotating sliding shaft 321, and makes the second limit tooth 322 mesh with the first limit tooth 3121, and is in an expanded state to support the lower end of the drawing board.

[0045] Specifically, the box body 1 is composed of a bottom plate and side plates enclosed around the bottom plate, and the box cover 2 is composed of a top plate and side plates enclosed around the top plate; the side plate at one end of the box body 1 and the side plate at one end of the box cover 2 are hinged by hinges, and the box body 1 and the box cover 2 are both integrally formed of aluminum alloy.

[0046] When the lower end stopper 32 is in the first working state, it rotates around the rotating sliding shaft 321 to the retracted state, pushing the lower end stopper 32 to drive the rotating sliding shaft 321 to slide in the slide rail assembly 31. When the lower end stopper 32 moves to a suitable height, the lower end stopper 32 is rotated to make the lower end stopper 32 and the rotating sliding shaft 321 rotate relative to each other, and the second limiting tooth 322 is meshed with a first limiting tooth 3121 on the limiting position 312. At this time, the lower end stopper 32 no longer moves and is in the expanded state. In this state, the user can place the drawing board above the lower end limit piece 32 to support the drawing board and facilitate the user to paint. Compared with the traditional structure of fixing the drawing board by tightening screws, the fixing method of the present application is simple. It only needs to rotate the lower end limit piece 32 around the rotating sliding shaft 321, and make the second limit tooth 322 engage with the first limit tooth 3121 to be in the expanded state. During the painting process, there is no need to worry about the relative movement of the lower end limit piece 32 and the first limit tooth 3121 causing painting errors.

[0047] Since the lower end limit piece 32 is in contact with part of the outer edge of the drawing board, the shape of the drawing board is less required. The present application is not only convenient for fixing square drawing boards, but can also effectively fix circular or other shaped drawing boards. It is easy to use and has a good fixing effect.

[0048] After painting is finished, rotate the lower end limit piece 32 so that the lower end limit piece 32 rotates around the rotating sliding shaft 321 to a folded state, and can slide in the slide rail assembly 31 until the lower end limit piece 32 slides to a suitable position. At this time, the larger surface of the lower end limit piece 32 fits with the inner side surface of the box cover 2, and the lower end limit piece 32 will not extend into the box body 1, and will not affect the layout of other objects in the box body 1.

[0049] like Figure 2-Figure 3 As shown, in one embodiment, a plurality of third limiting teeth 323 are provided on one side of the lower end limiting member 32 close to the limiting position 312 , and in the first working state, the third limiting teeth 323 mesh with the first limiting teeth 3121 on the limiting position 312 .

[0050] Specifically, when the drawing board does not need to be fixed, that is, in the first working state, the lower end limit piece 32 rotates around the rotating sliding shaft 321 to a retracted state. At this time, the third limit tooth 323 of the lower end limit piece 32 is engaged one by one with the multiple first limit teeth 3121 on the limit position 312. At this time, the larger surface of the lower end limit piece 32 is in contact with the inner side surface of the box cover 2, and the lower end limit piece 32 will not extend into the box body 1, and will not affect the layout of other objects in the box body 1.

[0051] When the drawing board needs to be fixed, that is, in the second working state, the lower end limit piece 32 can be rotated around the rotating sliding shaft 321, and the second limit tooth 322 can be meshed with the first limit tooth 3121 to be in an expanded state. At this time, the lower end limit piece 32 has a side with multiple third limit teeth 323 facing upward, and the user can place the drawing board above the lower end limit piece 32 to support the drawing board. The third limit teeth 323 can increase the friction between the lower end limit piece 32 and the drawing board, thereby avoiding the problem of the drawing board moving during the user's painting process.

[0052] like Figure 2-Figure 3 As shown, in one embodiment, a plurality of limit positions 312 are provided, and a plurality of first limit teeth 3121 are provided on each limit position 312 .

[0053] Specifically, there are at least a plurality of limit positions 312 between the two slide rails 311 , and the plurality of limit positions 312 are evenly spaced between the two slide rails 311 ; and a plurality of first limit teeth 3121 are disposed on each limit position 312 .

[0054] In a preferred embodiment, the number of the first limit teeth 3121 set on each limit position 312 is greater than or equal to the number of the third limit teeth 323 of the lower end limit member 32. In the first working state, the lower end limit member 32 rotates around the rotating sliding shaft 321 to a retracted state. At this time, the third limit teeth 323 of the lower end limit member 32 are meshed one by one with the multiple first limit teeth 3121 on the limit position 312. At this time, the side of the lower end limit member 32 with the third limit teeth 323 is tightly fitted with the inner side of the box cover 2, and the lower end limit member 32 is not easy to rotate and collide with other objects in the painting box.

[0055] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, in one embodiment, a second drawing board fixing member 4 is also included, and the second drawing board fixing member 4 includes a sliding member 41, a sliding groove 42 and a tension spring (not shown in the figure);

[0056] The sliding groove 42 is arranged on the inner side of the box cover 2, and the sliding member 41 is slidably arranged in the sliding groove 42;

[0057] One end of the tension spring is connected to the sliding member 41, and the other end is fixedly connected to the inner wall of the sliding groove 42;

[0058] An upper end limiting portion 411 is provided at the upper end of the sliding member 41. Under the action of the tension spring, the upper end limiting portion 411 applies a downward pulling force to the upper end of the drawing board and limits the upper end of the drawing board.

[0059] Specifically, when the drawing board needs to be fixed, the lower end stopper 32 rotates around the rotating sliding shaft 321, and the second stopper tooth 322 is meshed with the first stopper tooth 3121, and the lower end of the drawing board is placed on the lower end stopper 32 to support the lower end of the drawing board; then, the sliding member 41 is pulled to slide upward in the sliding groove 42 until the upper end stopper 411 abuts against the other end of the drawing board, thereby fixing the upper end of the drawing board. When the sliding member 41 slides upward in the sliding groove 42, the tension spring is in a relaxed state, and the tension spring applies a reverse force to the sliding member 41, thereby fixing the drawing board between the upper end stopper 411 and the lower end stopper 32.

[0060] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, the second drawing board fixing member 4 also includes a cover plate 43, and the cover plate 43 is covered on the sliding member 41. The sliding member 41 includes a plurality of sliding plates 412, and the upper ends of the plurality of sliding plates 412 are extended and connected to the upper end limit portion 411, and a first opening groove 413 is provided between the other ends of two adjacent sliding plates 412; the position of the sliding groove 42 corresponding to the sliding plate 412 is provided with a first slide 421, and the end of the first slide 421 away from the upper end limit portion 411 is provided with a second opening groove 422, and the two adjacent first slides are provided with a first slide 421. A third opening groove 423 is provided between 421; a second slide 431 is provided at the position of the cover plate 43 corresponding to the sliding plate 412, a fourth opening groove 432 is provided on the second slide 431, two adjacent second slides 431 are connected at one end away from the upper end limit portion 411, a fifth opening groove 433 is provided between two adjacent second slides 431, and the first opening groove 413, the second opening groove 422, the third opening groove 423, the fourth opening groove 432 and the fifth opening groove 433 are all arranged along the moving direction parallel to the sliding plate 412.

[0061] Specifically, the distance between the first slide 421 and the second slide 431 is equal to the thickness of the sliding plate 412, and a first opening groove 413 is provided between the other ends of the two adjacent sliding plates 412, which reduces the contact area between the sliding plate 412 and the first slide 421 and the second slide 431, and reduces the resistance between the sliding plate 412 and the first slide 421 and the second slide 431; the first slide 421 is provided with a second opening groove 422, and the second slide 431 is provided with a fourth opening groove 432, which further reduces the contact area between the sliding plate 412 and the first slide 421 and the second slide 431, and reduces the resistance between the sliding plate 412 and the first slide 421 and the second slide 431.

[0062] Furthermore, the first opening groove 413, the third opening groove 423 and the fifth opening groove 433 have the same width; the first slide 421 and the second slide 431 have the same width as the sliding plate 412, and the first slide 421 and the second slide 431 are both in contact with the outer periphery of the sliding plate 412 to support and limit the sliding plate 412, thereby facilitating the sliding plate 412 to slide quickly in the sliding groove 42.

[0063] like Figure 1 As shown, in one embodiment, two groups of first drawing board fixing members 3 are provided, and the second drawing board fixing member 4 is provided in the middle of the inner wall of the box cover 2 , and the two groups of first drawing board fixing members 3 are symmetrically distributed on both sides of the second drawing board fixing member 4 .

[0064] Specifically, the two groups of first drawing board fixing members 3 are symmetrically distributed on both sides of the second drawing board fixing member 4; when the drawing board needs to be fixed, the lower end limit member 32 rotates around the rotating sliding shaft 321, and the second limit tooth 322 engages with the first limit tooth 3121, which is in an unfolded state, and the lower end of the drawing board is placed on the lower end limit member 32 to support the lower end of the drawing board; thereafter, the sliding member 41 is pulled to slide upward in the sliding groove 42 until the upper end limit portion 411 abuts against the other end of the drawing board, thereby fixing the upper end of the drawing board, thereby fixing the drawing board between the upper end limit portion 411 and the lower end limit member 32.

[0065] like Figure 6-Figure 9 As shown, in one embodiment, it also includes a box cover 2 unfolding support member, and the box cover 2 unfolding support member includes a support arm 51 and a limiting column 53;

[0066] One end of the support arm 51 is rotatably connected to the inner wall of the box cover 2, and the other end of the support arm 51 is a free movable end, on which a third limiting tooth 323 is provided; a limiting groove 52 is formed on the inner wall of the box body 1, and a limiting column 53 is provided in the limiting groove 52; the free movable end on the support arm 51 can be inserted into the limiting groove 52, so that the third limiting tooth 323 is engaged and fixed with the limiting column 53, so as to support and fix the unfolded box cover 2 in a specific unfolding position.

[0067] Most of the prior art has a slide groove on the inner side of the box body 1 to allow the support arm 51 to slide in the slide groove. When sliding to a specific position, the support arm 51 is fixed by screwing the bolts on the outer side of the box body 1. For users with less strength, the bolts are easy to loosen during use, causing the box cover 2 to flip over, resulting in painting errors.

[0068] In the present application, a third limiting tooth 323 is provided at the freely movable end of the support arm 51. The user can overlap the third limiting tooth 323 on the support arm 51 with the limiting column 53. The operation is simple and there is no need to worry about the box cover 2 flipping over during use, thereby reducing accidents during the painting process.

[0069] Furthermore, the present application provides a plurality of third limiting teeth 323 at the free end of the support arm 51, and the user can selectively overlap the third limiting teeth 323 on the support arm 51 with the limiting column 53, which is simple to operate and has a good fixing effect. The present application provides two limiting grooves 52, which are respectively provided near the left and right inner walls of the box body 1; similarly, the limiting column 53 and the support arm 51 are also provided with two, which are respectively provided on the left and right sides of the painting box, so as to fix the left and right sides of the box cover 2.

[0070] like Figure 6 As shown, in one embodiment, it also includes a support plate 62 and a paint tray (not shown in the figure), and a receiving cavity is formed on the inner side of the box body 1, and the support plate 62 and / or the paint tray are placed in the receiving cavity.

[0071] Specifically, a plurality of support plates 62 are provided, and when not in operation, the plurality of support plates 62 and the paint tray can be stacked and arranged in the accommodating cavity.

[0072] Furthermore, one or more paintbrush fixing structures are provided on the inner wall of the box cover 2 for fixing or hanging paintbrushes. The implementation method can be snap-on, plug-in or other methods. For example, as a very simple method, Figure 1 As shown in the figure, the paintbrush fixing structure includes two pins 21 and a rubber band (not shown in the figure) arranged between the two pins 21. The rubber band is stretched, and the paintbrush is inserted into the stretched rubber band to fix the paintbrush on the inner wall of the box cover 2.

[0073] like Figure 8-Figure 10 As shown, in one embodiment, a support plate 62 fixing structure is further included, and the support plate 62 fixing structure includes a first embedding hole 61 formed on the left side and / or right side wall of the box body 1;

[0074] The support plate 62 includes a support plate 62 body and a clamping plate 621 bent on the support plate 62 body. The clamping plate 621 can be correspondingly embedded in the first embedding hole 61 to install the clamping plate 621 on the left side and / or right side of the box body 1 .

[0075] Specifically, the first embedding hole 61 is arranged in a direction perpendicular to the bottom of the box body 1 , and first embedding holes 61 are formed on both side walls of the box body 1 . The support plate 62 is supported by metal material, and one end of the support plate 62 is bent to form a clamping plate 621 , which is embedded in the first embedding hole 61 .

[0076] Furthermore, if a plurality of first embedding holes 61 are formed on a side wall of the box body 1 , the clamping plate 621 can be cut according to the size of the first embedding hole 61 so that the clamping plate 621 can be embedded in the first embedding hole 61 .

[0077] The clamping plate 621 is disposed perpendicular to the supporting plate 62 . When the clamping plate 621 is embedded in the first embedding hole 61 , the supporting plate 62 can be located either outside the box body 1 or inside the box body 1 .

[0078] Since the first embedding hole 61 is formed on the side wall of the box body 1, there is no need to set a fixing structure of the support plate 62 at other positions of the box body 1, which saves space in the box body 1 and is simple to operate, making it easy to install and remove the support plate 62.

[0079] like Figure 1 and Figure 6 As shown, in one embodiment, the side wall at the other end of the box body 1 is recessed toward the inner side of the box body 1 to form a slot 11 , and when the box body 1 and the box cover 2 are closed, the upper end limit portion 411 is embedded in the slot 11 .

[0080] Specifically, the upper limit portion 411 is embedded in the slot 11, so that it is located in the same plane as the outer surface of the other end of the box body 1, avoiding the upper limit portion 411 protruding from the other end of the box body 1. The upper limit portion 411 is embedded in the slot 11, which reduces the volume of the painting box without changing the internal capacity of the painting box, and has a beautiful appearance and is easy to use.

[0081] Furthermore, an annular hole is provided on the upper end limiting portion 411, and the shape of the annular hole is rectangular or elliptical. The setting of the annular hole is convenient for the user to lift and use.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
